5 History and principle of Image J Features and philosophy behind Runs Everywhere ImageJ is written in Java, which allows it to run on Linux, Mac OS X and Windows, in both 32-bit and 64-bit modes. Open Source ImageJ and its Java source code are freely available and in the public domain. No license is required.

6 History and principle of Image J Features and philosophy behind Data Types 8-bit grayscale or indexed color, 16-bit unsigned integer, 32-bit floating-point and RGB color. File Formats Open and save all supported data types as TIFF (uncompressed) or as raw data. Open and save GIF, JPEG, BMP, PNG, PGM, FITS and ASCII. Open DICOM. Open TIFFs, GIFs, JPEGs, DICOMs and raw data using a URL. Open and save many other formats using plugins. Stacks

7 History and principle of Image J Features and philosophy behind Image Enhancement Supports smoothing, sharpening, edge detection, median filtering and thresholding on both 8-bit grayscale and RGB color images. Interactively adjust brightness and contrast of 8, 16 and 32-bit images. Geometric Operations Crop, scale, resize and rotate. Flip vertically or horizontally. Color Processing Split a 32-bit color image into RGB or HSV components. Merge 8-bit components into a color image. Convert an RGB image to 8-bit indexed color. Apply pseudo-color palettes to grayscale images.

8 History and principle of Image J Macros Features and philosophy behind Automate tasks and create custom tools using macros. Generate macro code using the command recorder and debug it using the macro debugger. More than 300 macros are available on the ImageJ Web site. Plugins Extend ImageJ by developing plugins using ImageJ's built in text editor and Java compiler. More than 500 plugins are available. Toolkit Use ImageJ as a image processing toolkit (class library) to develop applets, servlets or applications.

9 History and principle of Image J Usage scenario PROBLEM TO HANDLE SOLUTION DIFFICULTY Basic tasks (basic adjustments, simple measurements) Existing functions in Image J Repetitive work (multiple measurements, series of transformations) Integrated macros Image J or recording and modifications of existing macros Complex projects Necessity of creating new functions, work with new image formats, communication with other applications (third party), etc. Writing plugins from scratch or modifying existing plugins in Java language

13 The Image J current ecosystem

14 Name Author/Maintainer(s) Description Initiated Status ImageJ ImageJ1 Wayne Rasband The current, stable version is known simply as "ImageJ" or sometimes "ImageJ1" or "IJ1" to differentiate it from ImageJ 2.0 (still in development) Active ImageJ2 ImageJDev ImageJ developers The ImageJDev project (this web site and associated community) is developing version 2.0 of ImageJ, referred to as "ImageJ2" or "IJ2" for short. It is a complete rewrite of ImageJ, but includes ImageJ1 with a compatibility layer, so that old-style plugins and macros can run the same as in IJ1. Dec Active ImajeJA Johannes Schindelin ImageJA is a project that provides a clean Git History of ImageJ1, with a proper 'pom.xml' file so that it can be used with Maven without hassles. It is what Fiji uses (see below) at its core. Jul Active Fiji Fiji contributors Fiji is Just ImageJ, with extras. It is a distribution of ImageJ with many plugins useful for image analysis in the life sciences, an automatic updater, and improved scripting capabilities. It is actively maintained, with updates released often. We recommend Fiji as the preferred version of ImageJ. Dec Active MBF ImageJ Tony Collins The MBF "ImageJ for Microscopy" bundle (formerly WCIF ImageJ) is a collection of plugins and macros, collated and organized by the MacBiophotonics facility. It went hand in hand with a comprehensive manual describing how to use the bundle with light microscopy image data. It was a great resource by microscopists, for microscopists. Unfortunately, the manual went offline in late Nonetheless, it is often possible to add specific plugins from MBF ImageJ to a Fiji installation, combining the best of both programs Defunct (Last update: Dec. 2009) ImageJ2x Rawak Software ImageJ2x is a fork of ImageJ1, modified to use a Swing interface. Unknown Last update: Sep SalsaJ EU-HOU SalsaJ is a closed-source fork of ImageJ1 intended for use with professional astronomy images. It was designed to be used in classrooms, and has been localized into over 30 different languages. Unknown Last update: Aug ImageJX Grant Harris ImageJX was created as a means to discuss and explore improvements to ImageJ. There was an ImageJX mailing list as well as an ImageJX software prototype. The ImageJX software prototype was a proof of concept an attempt to reorganize ImageJ's internals to make it more flexible. The prototype demonstrated this flexibility by recasting the program in Swing. The ImageJX project formed the basis of an application to NIH for funding, which is what launched the ImageJDev project (see above). Mar Superceded by ImageJ2 NIH Image Wayne Rasband NIH Image is a public domain image processing and analysis program for the Macintosh. It is the direct predecessor of ImageJ, and is no longer under active development (though see ImageSXM below) or earlier Superceded by ImageJ ImageSXM Steve Barrett Image SXM is a version of NIH Image that has been extended to handle the loading, display and analysis of scanning microscope images.
